AB  - The electrically conductive poly (lactic acid) (PLA)/recycled high-density 
      polyethylene (HDPE)/carbon black (CB) composites with a fine co-continuous micro 
      structure and selective localization of CB in the HDPE component were fabricated 
      by one-step melt processing via a twin-screw extruder. Micromorphology analysis, 
      electrical conductivity, thermal properties, thermal stability, and mechanical 
      properties were investigated. Scanning electron microscope (SEM) images indicate 
      that a co-continuous morphology is formed, and CB is selectively distributed in 
      the HDPE component. With the introduction of CB, the phase size of the PLA 
      component and the HDPE component in PLA/HDPE blends is reduced. In addition, 
      differential scanning calorimetry (DSC) and thermos gravimetric analysis (TGA) 
      results show that the introduction of CB promotes the crystallization behavior of 
      the PLA and HDPE components, respectively, and improves the thermal stability of 
      PLA70/30HDPE/CB composites. The electrically conductive percolation threshold of 
      the PLA70/30HDPE/CB composites is around 5.0 wt %, and the electrical 
      conductivity of PLA70/30HDPE/CB composites reaches 1.0 s/cm and 15 s/cm just at 
      the 10 wt % and 15 wt % CB loading, respectively. Further, the tensile and impact 
      tests show that the PLA70/30HDPE/CB composites have good mechanical properties. 
      The excellent electrical conductivity and good mechanical properties offer the 
      potential to broaden the application of PLA/HDPE/CB composites.
